typewriting machines, wherein provision is had for feeding a fan-folded web upon a table in the direction of the platen, so that I theplaten may engage one end of said web and advance the same through the usual linespacing mechanism as the web is being typed.

In such types of machines a drawback has existed inasmuch as the weight of the relatively heavy carbon-carrier uponwhich the web is clamped during its movement in the direction of said platen with the added weight of the web' and interleaved carbon sheets causes enough inertia to make the rotatable platen, during the line-feeding action thereof, slip relatively to the web, so as to be ineffective to feed the web uniform line space distances. 4

One of the objects of the present invention This invention relates to improvements in ]S to overcome this disadvantage, as here-- inbefore explained, by simple, efiicient and inexpensive mechanism so constructed, designed and arranged upon the table ,over which the .web is fed along towards the platen that the web may be slackened just previous to the action .ofrotating the platen, duringthe line-feeding operation. The so slack thus introduced in the web may be the platen is su denly and manually actuated by the line-spacing mechanism or by means of operating automatically during the return of the carriage by motor-operated 3 mechanism, such as is shownin the patent to Hart N0. 1,325,469, dated December 16, 1919, the line-spacing of the platen takes up the slack in the web between the carboncarrier and the platen.

Another object' of the present invention is to provide simple mechanism for automatically advancing the carbon-carrier, so thatthe web clamped thereonto may be fed along over the table intermittently and timed with the actuation of the line-spacing mechanism, so that the carbon-carrier is movable forwardly in the direction of the platen at the same time that the platen is itself rotated by the line-spacing mechanism. The result of this mechanism is to remove all stress from the web in advancing the carbon-carrier toward the laten.

A still urther object of the present inoperative to revolve the equal to a line-dpace distance, and when vention is to assure that the carbon-carrier, Y which feeds the web along toward the platen 66 by an actuation of the line-spacing mecha-' nism, is advanced in rolling contact upon the table just before the line-space slide is cylinder or platen, so that the initial movement of the carbon- 00 carrier creates slack betweenthe'cylinder and the carrier before the cylinder is line spaced to advance the forms and when the forms are carried around the platen, the

'slack in the web is taken up and there is no 5 jerk or stress exerted upon the web necessary to overcome the inertia of the web-carbons and carbon-carrier, and no slipping of the cylinder or the platen relatively to the weband carbon-carrier can take place;

Heretofore carbon-carriers have been equipped with web clampsservin to clamp i the web onto a carrier to cause it to move along with the latter. During the forward operative traverse of the carrier, the means, i

which has been provided for manually disengaging the clamp on the carrier from the web, is rendered inactive until during the reverse movement of the carrier to carbon released position. Such manual cIamp-releasing means in conventional use has called for the action of two handle bars, one-of which is fixed upon the carriage and the other of which moves relatively thereto and is effective to actuate the Vice. 7 I

' In such types of cinvention, however,-the clamp actuating and releasing handle bar had to be actuated by apush action, which required special attention on the part of the operator, in a manner which is disclosed clearly in the U. S. patent to Smith, No. 1,364,819, granted January 4, 1921. -.In said patent it is necessary to pull the clam operating finger-piece forwardly, while t e fixed finger-piece is'held bythe thumb. In. the. present invention, means is provided by which the carbon-carrier may also be re-. tracted without releasing the web, if desired, by engaging the fixed handle instead of the 100 floating handle. Furthermore, in operating the floating'handleof the present invention to release the clamp from engagement with the web, a pulling action is exerted upon the floating handle for this purpose instead of a pushing action, so that one hand of the web-clamping deoperator can effectuate the release of the clampwvithout undue exertion and w thout -irksome labor.

Referring to the drawings, which are merely illustrative of the invention, 10 desi ates the front rail of a typewritin mac ine, preferably the Underwood stanr ard machine, which carries the calibrated rule 11 and relatively to which moves the carriage 12, the rollers 13 of which are guided upon the rail 10. 14 designates the aide-plate in which a line-space lever 15 1s movably operated, this lever being fulcrumed at 16, at which point it is provided with a push arm 17 for pushing the spacer slide 18 in a conventional manner against the tension of a sprin' 19.1ocatcd in the housing '20 in which t e spacer slide 18 moves. 7

21 designates the usual line-space regulator determining the number of lines over which the web is to .be fed by means of the platen 23, and 22 designates the linger-knob of the platen 23. H l

During the actuation of the conventional spacer slide 18 for line-spacing purposes the y rotated and meshes with gears 25 to rotate the platen and linespace the web.

The present invention is automatically and intermittently actuated by the linespacing mechanism, and is connected to the latter by a link 26secured at one end upon a pin 27 of the slide 18, upon which pin is also located-the spring 19 for restoring the slide 18. One arm of the link 26, designated 27, inclines upwardly and rearwardl and is twisted at 29, to change the plane t ereof for a continuing arm 28 whichvis connected by a pin 30 to a lever 31, fulcrumed between its ends to a pin 32 fixed upon a bracket arm 35, connected to the carriage 12 of the machine. The lever 31 has a toe 33 between which is connected the rear bar 41 and a front bar 42, the longitudinal bars connecting the front and rear bars 42 and 41 respectively. The table may be conventional. Rollers 43 are suitably journaled upon the 111K161 side of the table in brackets 44 and make rolling contact with a rear rail 45 of the machine, which is secured upon a frame 46 mounted upon the main frame 47 of the machine by. connections (not shown). The carbon-carrier is designated 48, and operatively mounted thereupon, at each end thereof, are rollers 49 which make rolling contact with longitudinal rails 50 upon the table 39. This carbon-carrier 48 consists preferably of a baselate 51 upon which are secured, adjacent eac end, stepped uprights 52, which carry carbon-blades 53, usually arranged in superimposed and staggered relation and to which the carbon-sheets are attached to be interleaved between the folds or plies of a fan-folded work-web 54 well known to those skilled in the art. This web travels from a supply-roll cSnot shown) over the turnin bar 55 mounte in standards 56, between side uides 57 mounted upon the turning bar or guiding the longitudinal edges of the web in proper relative position upon the carbon-carrier.

The longitudinal rack-bar 58 has racktceth 59 extending lon itudinally thereof practically throughout t e entire length of the table, Shouldercd screws 60 with heads that form a flange are secured at spaced apart points upon the rack-bar 58 and serve as studs within slots formed upon camplates 64 which are secured upon the table 1y means of screws 65 projecting through spacer sleeves 66 which s ace the plates 64 in a plane parallel wit the table 39, as is clearly shown in Figure 4. The forwardly-pro ecting edge 67 of each plate 64 positions the plate 64 in such a manner that the rack-bar 58 is ositioned normally medially thereof. Eaci slot formed in the cam-plates 64 consists of a longitudinal straight slot or track 61 ando positely inclined diagonal recesses 62 'a' 63 opening into said straight slot 61 andrserving to cam the 'studs 60 on the rack-bar 58 which project therethrough, to romote a parallel movement for the rackar 58. a

A retractihle spring 68 is secured at one end fixedly to a pin 69 on each plate 64 and has its terminal secured on a pin 70 fixed upon the rack-bar 58, for normally holding tc studs 60 againstv the inner edge of one of the diagonal recesses 62 or 63 of each plate 61, and in this position of the studs 60 it will be seen that the rack-bar 58 is held longitudinally of the table and against movement thereon, and at this time the toe 33 of the'lever 31 disposes the lever 31 ob liquely of the longitudinal axis of the rackbar 58, the spring 19 in the housing 20 of the line-spacing mechanism assisting to so position this lever 31.

The carbon-carrier has secured to the under side of its base-plate 51 a foot 84 of a bracket 71 secured thereto by fasteners 85 and fori'ned with a lip 72 parallel to the foot, to which a stud 73 is fixed by a screw threaded into the lip and having a head 74 overlying the lip 72, said stud serving as a center or fixed pivot upon which is tulv crumed a pawl 75 having a nose 76 at one end and formed with a notch or recess 77 at its opposite end to coact with a fixed pin 78 secured 'upon the lip 72. A spring 80 is coiled snugly within a groove 81 of acollar 79 formed upon the stud '73, and this spring has one terminal 82 secured in the collar 79 and its other terminal 83 secured to the pawl 75. Normally the spring causes the nose 76 of the pawl 75 to project beyond the lip 72 endwise of the carbon-carrier 48.

The rails 50 are secured upon bars 40, the sleeves 66 contacting with the bars 40 being held thereto by the screws 65, already explained. The rollers 49 are journaled in supports 87 which are secured to the baseplate 51 of the carbon-carrier 48,

89 designates a bar which at its inner end curves downwardly and is fixedlysecured upon a. side piece 90 extending upwardly from the carbon-carrier 48 at one side. Pins 91 are secured respectively one upon the side piece 90 of the base-plate 51 of the carbon-carrier 48 and the other uponthe base-plate 51, and serve to support the inner ends of springs 92, .the opposite ends of which springs are secured upon pins 93 fixed upon the side arms 94 and 95, respectively, of a clamping device. These arms 94 and 95 are fixed at the ends of a shaft 96 journaled in the stepped uprights 52 on the carbon-carrier 48 having its intermediate portion ofiset at 97. The side arm 95 is provided with a cam-recess 98 to coact with a roller 99 journaled upon one arm 100 of a hell-crank lever fulc-rumed between its ends upon a pivot 102 fixed upon the side piece 90. the other arm 101 of said lever carrying a screw 103' upon which is pivoted the curved end 104 of ashifting or floating bar 105, the latter floating bar 105 having an elongated slot 106 in which slidably projects a headed stud 107 fixed to the bar 89, the free end of the bar 105 projecting beyond and in advance of the bar 89, both bars 89 and 105 being provided with suitable finger-pieces 10s and 109.

A plate formed with a longitudinal groove 110 thatv extends transversely across" and in .frontgofsaid carbon-carrier 48 is secured to the latter by screws 112. The side arms 94 and 95 of the'clamp device are formed with ears 113 to which is secured a movable clamp 111, which inaybe employed to depress the web 54 into the groove 110 in i the plate for clamping purposes, as shown clearly in Figure 4.

In Figure 4 it will be noticed that the table 39 is supported in horizontal position rearwardly of the platen 23, so i that the rails 50 are spaced above the housing 20 in which is mounted the spacer slide 18. The table in this case is raised to the elevated position shown in order to provide clearance for the tabulating mechanism 123; However, in Figure 8, it will be noticed that the table 39 is in a lower plane with respect to the corresponding parts of the machine than it is shown to occupy in Figure 4, because the tabulating moved in this instance, thereby permitting the rails 50 of the table 39 to be disposed virtually at the same level with the bottom of the housing 20, the housing 20 be ng below the table in Figure 4. The link 26 shown in F igure-4 is serviceable to connect the slide 18 and the rack-operating lever 31. In Figure 8, the housing 20 is located above the table 39, thereby necessitating a different construction and shape, of this connecting link. This latter link 26 is attached to the spacer slide 18 in the same "manner as is shown in Figure 4, and has the horizontal "projecting arm 115 which inclines downwardly at 116 .so as to be connected to the rack-bar 58. The arm 116 of the link 26 curves around reversely at 117 I and is twisted at 118' to provide an ear 119, which is secured to the outer end of the lever 31 by a screw 120, ,said lever being fulcrumed upon one of two arms 121, secured to the carriage 12. The arms 121 have ears 121 (one being shown in Figure 8), through which screws 122 pass and thread into the ends of the front bar 42 of the table 39. By means of this construction, the link 26 is spaced downwardly to the level of the table 39, operating in all other respects the same as the link 26 shown in Figure 4.

The mode of operation of the present invention is as follows: The fan-folded web or other work-web 54 is advanced from a feed-roll (not shown) or other source of supply therefor, .and is turned over the turning bar 55 of the frame of the table, and from this point the web is usually pulled over the table, and underthe platen 23 during the line-space action of said platen.

But owing to the fact that the weld is engaged by the carbon-carrier, it becomes necessary to overcome the inert-ia of both the web and the carbon-carrier in the act of mechanism 123 is readvancing the web through the medium of said platen 23. This has occasioned quite often the slippage of the platen relatively to the web, especially when the return of the rotates to frietionally take up the advancing web, the web has already been slightly advanced automatically, so that there is slack in the web at the moment that the line-spacing mechanism begins to rotate the platen.

As the line-spacing mechanism operates, the spacer slide 18 in the conventional mannor is slid along this housing 20 after the line-space lever has been moved in its guideplate 14. As the spacer slide 18 moves, suitable connections including a line-space ratchet-wheel (not shown) operate the pinion 24, which, in turn, meshes with the gears 25 to rotate the platen. As this spacer slide moves it pushes the link 26 rearwardly, as shown in dotted lines in Figure 1, which, in turn, shifts the lever 31, causing the toe 33 of the latter to move toward the right, thereupon causing one reciprocation of the rack-bar 58 to take place. The lever 31 moves the rack-bar 58 longitudinally of the table in a forward direction toward the platen, and springs 68 and 19, at the completion of the line-spacing operation, serve to retract the'link 26 and lever 31, and to retract the rack-bar 58 in a rearward direction and thus work a complete reciprocation.

Immediately as the rack-bar starts upon its forward movement, the studs 60 mounted thereon occu y their normal positions at the inner ends 0 the diagonal recesses 62 of the slots formed in the cam-plates 64, and the teeth 59 of the rack-bar are out of engagement with the pawl 75. As the rack-bar moves forwardly the studs 60, moving therewith, ride forwardl in both a longitudinal and a transverse (irection, owing to the inclination of the recesses 62, so that the rack-teeth 59 move transversely into engagement with the nawl mounted upon the carbon-carrier, and thus exert a forward movement upon the carrier in thedirection of the platen. By

move longitudinally in the longitudinal tracks 61 of the cam-plates 64, during the continued movement of the rack-bar 58, the carbon-carrier has been moved a short distance, while the platen 23 is still inactive,

the time the studs 60- being so timed to perform'this rot-alive function by said spacing mechanism. As the rack-teeth engage the pawl, the latter cannot swing on its pivot 73 because the pin 7 8 in the recess "4 acts as a stop to prevent this pivotal movement, which movement takes place'only during the return movement of said rack-bar 58. i

Inasmuch as the clamped to the carbon-carrier 48, owing to the engagement of the clamp 111 within the groove 110, and owing to the fact that the carbon-sheets (not shown), which are supported upon the carbon-blades 53, are properly interleaved between the several plies of the fan-folded web 54, it follows that this work-web together with the mentioned carbon-sheets are caused to move in unison with the carbon-carrier 48. Therefore, during the slight initial forward movement of the carbon-carrier longitudinally of the table, as

a result of the studs 60 riding out of the dia 'onal recesses 62 of the cam-plates 64, a slight loop or slack is created in the web 54 immediately in back of the platen 23. At this point and while the studs 60 are traversi ing the longitudinal or straight tracks 61 of the slots, the platen 23 is rotated by the linespacing mechanism, which also is responsible for the last-named movement of said studs, and, in rotating,- said platen, which is in frictional engagement with the workweb, owing to the usual feed-rollers (not shown), exerts a pull upon the loop portion of the web more or less suddenly, so while the carbon-carrier continues its forward motion synchronously withthe rotation of the platen there is slack upon the web during this operation. The studs 60, while the platen is still rotating, are caused to be cammed into the other diagonal recesses 63 of said slots in the cam-plates 64 against the .tension of the spring 68 which holds these studs stationary in the last-named recesses, thereby shifting the rack-bar 58 laterally back to its first-named normal position and retracting the rack-teeth 59- from engagement with the pawl 75. This results in the carbon-carrier automatically stopping, at which time the platen also stops having" .taken up the work-web 54 a distance equal work-web 54 is releasably until the advancing ed mal position, thereby pushing the rack-bar rearwardly, therefrom are impelled out of the diagonal recesses 63, thereby re-engaging the rackteeth 59 with the pawl75 of the carbon-carrier. At this time the nose 7 6 of the pawl is forced backwardly against the tension of the coiled spring 80 as the studs 60 traverse the straight tracks 61 of the slots and ultimately,

as these studs return to normal position after rlding into the diagonal recesses 62, the rack-teeth 59 are then retracted from said pawl. During the rearward movement of the rack-bar 58, therefore, the pawl re-engages the teeth of the rack-bar without imparting movement to the carbon-carrier. The carbon-carrier, therefore, remains sta-' tionary until the next operation of the linespacing mechanism already explained.

The carbon-carrier is fed along until it reaches the end of its forward movement and is' located upon the table adjacent the front bar 42. At this time a printed form on the work-web has been typed sulficiently to be ready for a severing action. Usually the mentioned printed form hasits last line typed at a point spaced from the division line between this form and the next printed form' about .tobe t ped, so that before the printed form alrea typed can be detached along the tearing-o knife (not shown), the operator depresses the release handle 114 of the swinging platen-frame and brings the platen toits lower forward position, thereby also positioning the gage-member 124 secured to the swinging platen-frame in horizontal. position. Now by releasing the feedrollers (not shown) engaging the under surface of the platen,-the operator, while still holding the printed form, pulls the same along and with it the web and carbon-carrier of said printed form is properly gage printed form is detached. It will be understood, however, that before detaching the printed form, the operator engages the finger-piece 108 of the fixed bar 89 and at the same time engages the fingerpiece 109 of the relatively slidable or floating bar 105, the action being such that the two finger-pieces are caused to interengage after sliding the finger-piece 109'toward the fixed finger-piece108, as shown in dotted lines in Figure 4. By thus shifting the floating bar 105, the bell-crank-lever-arm 100 is turned upon the fixed pivot 102, which causes the roller 99 to be raised as it is slidably guided in the cam slot or recess 98 formed '11 on the side arm 94 of the clampdevice, w llCll action raises this end of the clamp-device on the shaft 96 which acts as a fulcrum point therefor; The raising of the clamp device takes place against the tension of the retractible'springs 92, so that the clamp 111 proper is disengaged from so that the studs 60 depending 1y separating the carbon-sheets from contact tually after which this contact with the work-web 54, thereby loose with the plies of the work-web.54.

While the finger-pieces 10s and 109 have i been brought together to the dotted position shown in Figure 4, the carbon-carrier may be shifted rearwardly, the release of the clamp taking place almost instantly. As the carbon-carrier is retracted, the carbonrsheets held upon the blades 53 are moved with the carrier and are stripped from the printed forms. During the rearward movement of the rack-bar 58, the pawl mounted on the carbon-carrier is disengaged from the teeth of the rack-bar, and the arrangement of the floating bar 105 with respect to the'fixed bar 89 of the carbon-carrier is such that one hand of the operator or typist-can eflecmove the carbon-carrier upon the table while at the same time releasing the clamp on the carbon-carrier from engagement with the work-web, and it is not necessary for one hand of the typist to hold the carbon-carrier while another hand is engaging the floating fingeriece with a pull action thereon in order to e ect release of the clampfrom contact with the work-web, as is found necessary in previous devices.

It will noted that the Underwood linespacing mechanism provides for a sweeping line-spacing movement of the line-spacing lever to effect a triple line-spacing rotation of the platen; that when the line-spacing devices are conditioned for a single linespacing operation, the line-spacing lever has the same sweeping stroke and idly swings through an inactive are before becomin effective to rotate the platen; that during this inactive initial sweep of the line-spacing lever, the rack-bar 58 is conditioned to engage with the pawl 75 of the carbon-carrier 48,

and during the initial forward movement of the studs 60 over the flat tracks 61, said carrier is drawn towards the platen to create a slack in the composite web; that while the studs 60 are still upon the tracks'61, the linespacing mechanism becomes active to rotate the platen; that during the remainder of the travel of the studs 60 along the tracks 61, the carbon-carrier is fed inunison with the surface feed of theplaten to maintain the slack in the web; that when the studs 60 begin movement of the studs 60 to bottom within.

the recesses 63, the line-spacing mechanism is effective to rotate the platen and take up the slack in the webs between theplatn an the now stationary carbon-carrier; that when the studs 60 bot-tom within the recesses 63 and further forward movement of the rackbar 58 is arrested, the line-spacing connections to the platen are simultaneously arrested at the end of the line-spacing movement; and that during the whole linespaeing movement, no stress has been placed upon the section of webs between the platen and thecarbon-carrier, and the only drag attached to the platen-feeding of the web is in drawing the short section of the web towards the platen. While the arrangement and proportions of the parts have been described t'or a single line-spacing operation of the webs around the platen, the relative length of the tracks 61 between the recesses 62 and 63 may be such that records may be made on the webs that will be uniformly separated by two or more line-space distances.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
